Weather Underground Forecast for Tuesday, May 21, 2013.

After a devastating severe weather day in the Plains on Monday, severe weather is expected to fire up again across the nation's mid-section again on Tuesday.

The nearly stationary low over the Northern Plains will gradually weaken as it shifts eastward into the Midwest on Tuesday, while the system's associated cold front trails southwestward from the low across the Mid-Mississippi Valley through the Southern Plains. Favorable energy and conditions ahead of the cold front combined with the moisture laden conditions of the nation's mid-section will set the stage for multiple clusters of thunderstorms to develop from the Midwest into the Ozarks and the Southern Plains. Portions of northeastern Texas, extreme southeastern Oklahoma, central and southern Arkansas, and northwestern Louisiana are at moderate risk of severe thunderstorm activity as environmental conditions remain favorable for tornadoes, damaging wind gusts, and very large hail. Areas surrounding this moderate risk region from the parts of central and eastern Texas into the Upper Great Lakes are at slight risk of severe thunderstorm development with hail, damaging wind gusts, and isolated tornadoes.

Meanwhile, areas of heavy rain and widely scattered showers will continue near the low in the Northern Plains and Upper Mississippi Valley and near and to the north of a nearly stationary frontal boundary extending out ahead of the system from the Great Lakes into the Northeast. Continued precipitation in already saturated areas of the Northern Plains and Upper Midwest will maintain flood concerns from parts of North Dakota into northern Wisconsin.

Elsewhere, scattered showers and thunderstorms are expected to persist in the Mid-Atlantic and southeastern corner of the nation.

Mobile & Email Alerts Statement as of 9:00 am CDT on March 21, 2013

... This is safe boating week...
... Marine forecast...

The following is a safe boating message from the National safe
boating Council and the National Weather Service.

Understanding a marine forecast is critical to safe boating.
Weather and wave conditions can change suddenly... catching boaters
off guard and creating life threatening conditions.

Typical marine forecasts predict wind speed and direction... wave
heights and periods... roughness of near shore waters... and
significant weather. Marine forecasts cover large areas and the
forecast elements are often given in ranges. The significant weather
may not occur over the entire area or during the entire forecast
period. The ranges represent average conditions over a period of
time... usually 12 hours... and the actual conditions may be lower or
higher than the forecast range. Boaters should plan for conditions
above and below the predicted ranges.

Take particular note of any current advisories and
warnings... including small craft advisories... gale or storm warnings
which alert mariners to either high winds or waves occurring now or
forecast to occur up to 24 hours from now. Special marine warnings
are issued for sudden increase in winds to over 35 knots... 40
mph... waterspouts... tornadoes over water... and hail of three
quarters of an inch of greater and indicate a more immediate threat.
Marine weather statements bring attention to significant rapidly
changing conditions on the water including increase in winds... non
severe thunderstorms... development of dense fog and even snow
squalls or strong and gusty rain showers.

You should have a marine vhf transceiver with build in NOAA Weather
Radio channels. If you venture beyond about a 25 nautical mile range
from shore... you should consider buying a good quality hf single
sideband transceiver and satellite phone.

Before setting out... obtain the latest marine forecast and warning
information from www.Weather.Gov/marine or NOAA Weather Radio.
Several days ahead of time you can begin listening for extended
outlooks which give general information out o the next five days in
both graphical and text format.
